Advances on Analysis of Triacylglycerols in Plant Oils Based on Chromatography Methods

Triacylglycerols (TAGs) profiling of plant oils is important for the effective control of edible oil quality and the safety assurance of plant oils. The analysis of TAG compositions in plant oils is a challenging task because of the complicated compositions of TAGs and their similar physico-chemical properties in plant oils. In this article,all kinds of chromatography technologies for the analysis of TAGs were reviewed. The advantages and disadvantages of these analytical methods and the relevant applications in TAGs analysis were also described. In addition,the applications of fingerprint technique and chemometrics methods in the identification of plant oils were also introduced.
